Current manager Erik ten Hag, though, has a more laid-back approach, allowing players to wear club tracksuits for away games. This is a change from Ole Gunnar Solskjaer’s time as manager too, when the former forward reinstated a stricter dress code during his spell in the hot-seat.

Foster shared some memories of his time under Sir Alex Ferguson, saying via the Mirror: “When I was at United, with Sir Alex Ferguson, that was the bare minimum. Hitting the standard was the bare minimum.

Should Ten Hag bring back the rule? Let us know in the comments below.

“I remember, if we would play away and we would fly, then we would get on the plane and you would get changed almost instantly. You arrive, you’re in your suit, you’ve got your tie on. Everything’s done.

“You don’t even dare not have your top button done up, tie to the top, perfect. You look immaculate. You’ve got your shoes on shined. The second you get on the plane, you would take your suit off, put it into its hanger and hang it up all nicely.

“Everybody is labelled up nicely. You would get into leisurewear shorts, T-shirt and everything like that. It might be a three-hour flight, it might be a six-hour flight. Within half an hour of landing, it would be ‘right lads, everybody back in your seats get dressed again’.”

Why Ten Hag decided to relax the rule is unknown. But if a suit and tie could boost United’s performance on the pitch, maybe he should consider bringing it back – and quickly!
